Stent having tapered aortic struts



FIG. 1 is a front perspective view of a stent having tapered aorticstruts according to my new design;

FIG. 2 is a front elevational view of thereof;

FIG. 3 is a rear elevational view thereof;

FIG. 4 is a right side elevational view of thereof;

FIG. 5 is a left side elevational view of thereof;

FIG. 6 is a top plan view of thereof;

FIG. 7 is a bottom plan view of thereof;

FIG. 8 is an enlarged front elevational view of a portion of FIG. 2; and

FIG. 9 is an enlarged front elevational view of a section of FIG. 8,which is an enlarged strut of the stent having tapered aortic strutsaccording to my new design.

FIG. 8 is an enlarged front elevational view of a portion of FIG. 2.FIG. 8 illustrates a pattern of three one-half cells of the stentadjacent one another, wherein each one-half cell includes two struts. Asshown, a central one-half cell is positioned in the middle or center ofthe three one-half cells. The central one-half cell includes two strutsthat do not taper along their respective lengths. A first one-half cellis positioned to the left of the central one-half cell and a secondone-half cell is positioned to the right of the central one-half cell.Each of the struts of the first and second one-half cells that areadjacent the central one-half cell tapers at some point along itsrespective length; and,

FIG. 9 is an enlarged view of a single strut, as shown in FIG. 8, whichillustrates the taper of the single strut. A second strut is shown inFIG. 8 directly to the left of the single strut. The second strut is amirror image of the single strut taken across a plane that extends alongthe y-axis and possesses the same shape and configuration as the singlestrut.

The pattern shown in FIG. 8 of a central one-half cell with first andsecond adjacent one-half cells continues around the circumference of thestent, such that there are two additional patterns of a central one-halfcell with adjacent one-half cells positioned on each side of the centralone-half cell.

Each of the struts in the two additional patterns that are oriented inthe same positions as the struts shown in FIG. 8 possess the same shapesand configurations as the struts shown in FIG. 8. As shown, the strutsof the central one-half cell in the two additional patterns do not taperalong their lengths. The struts in the first and second one-half cellsthat are adjacent the central one-half cell in the two additionalpatterns, however, do taper along their lengths. In particular, thestruts in the two additional patterns that are oriented in the sameposition as the single strut shown in FIG. 8 and enlarged in FIG. 9 willpossess the same shape and configuration as the single strut shown inFIG. 9. The struts in the two additional patterns that are oriented inthe same position as the second strut shown in FIG. 8 will possess thesame shape and configuration as the second strut shown in FIG. 8.

The broken lines shown in the drawings illustrate environmentalstructure and form no part of the claimed design. The dot-dash linesrepresent boundary lines and form no part of the claimed design. It isto be understood that the claimed design extends to but does not includethe defined boundary.

CLAIM The ornamental design for a stent having tapered aortic struts, asshown and described.
